To @ZZ whom t may concern: y

Be it known that LANDREWC. COLLEY, of Eclectic, in the county of Elmoreand State of Alabama, have invented certain new and nseful Improvementsin Locks; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which formpart of this specification, in which-4 Figure lis a face view of myimproved lock with the cover removed. Fig.2 isan oblique transversesectional view on line 2 2, Fig. l. Fig. 3 is a vertical sectional viewon line 3 3, Fig. 1. Fig. 4 is a transverse vertical sectional view online 4 4, Fig. l. Fig. 5 is a view of the oscillating lever detached.Fig. 6 is a View of the cam-disk detached. Fig. 7 shows the toothedsegment detached.

This invention is a lock; and its objects are to provide improved meansfor operating the bolt independently of the key and yet control theoperating devices by mechanism the bolt, so that the bolt cannot beoperated, even if the positive dogging device be thrown back or releaseduntil the bolt-operating de-V vices are thrown into gear; and to theseends the invention consists in the novel construction and combination ofparts hereinafter fully described, and summarized in the claims.

Referring to the drawings by letters, A represents the case; B, the boltsliding longitudinally in the case in proper guides and having astop-lug b playing in a recess c in the case to limit its throw, and arecess B',

moving in suitable guides in the case and lying at right angles to thebolt. The dog can only engage` the bolt when the latter is projected orlocked The dog overlies a pivoted tumbler D, which is pressed toward andbeneath the dog by a spring d. Said tumbler has an upstanding tooth D',which is adapted to engage either of two notches c cin dog C and lockthe same in or out of engagement with boltB.- Theinnerface of dog C'isnotched, as at C', and the tumbler D projects beyond the point of thenotch, so that-if a key be 5o allowing the latter to be moved up or downby the key. Below and to the inside of the dog and tumbler is asmall'cam-disk E, journaled on a round stud e, fixed to the case; Thedisk partially underreaches the edge of the dog, and on its upper face,near its periphery, is a series of grooves or recesses E E', separatedby lugs or stops E2. On the lower face of theldisk is a single roundedlug 0r cam E3, which is adapted to engage the end of an oscillatingleverF, which is pivoted near its center in a loop or lugs attached tothe frame and lies obliquely in the frame, its lower end underlying theedge of disk E and being doubly beveled, as at F F2, so that as the diskis turned right or left its cam E3 will engage and depress the end ofthe lever. The opposite end of the lever is bifurcated and partlyembraces a grooved clutch-wheel G, having` studs f, which enter theperipheral groove g3 ofl said clutch, so that if the lever be oscillatedthe clutch Gr will be raised or lowered and yet at all times can berevolved freely with the shaft. This clutch has an angular bore 4g andupstanding pins or lugs g on its face, which are adaptedtoenter-recesses It h on the inner face of a revoluble tumbler or segmentH, which is loosely mounted on a shaft I, which is squared near itsinner end to it the bore of clutch G, and has a reduced journal t' onits end bearing in a proper recess in the case, While its outer end isl:jonrnaled ina bearing in the front or cover of the case, and on saidshaft may be fixed knobs or handles I for revolving it.

J designates a spring placed between the beveled end of lever F and therear of case and forces said end outward against the disk E, thusnormally keeping pins g of wheel Gr out of engagement with the recessesh of segment H. The segment has a series of teeth h', which engage teethZJ on the bolt B.

Theoperation is about as follows: When the bolt is properly projected,(locked,) as shown in Fig. l, it is dogged by the engagement of dog Owith recess B and thus positively fastened, and the dog is secured bytumbler D, while the cam E3 is out of engagement with lever F.Consequently clutch G is disengaged from segment H, and the shaft I canbe revolved without any effect on the segment. To unlock or throw backthe bolt, a key is inserted through the key-hole above disk E, the keybeing so constructed that the bottom edge of its flange will engage oneof the stops E2 and revolve the disk, and its end will enter the notchin dog C as the key is turned, and first force back tumbler D and thenwithdraw dog C out of engagementwith bolt B, and as the disk is revolvedcam E3en-.

gages and oscillates lever F, throwing clutch G into engagement withsegment H, so that when it is again turned by shaft I the bolt can beslid back or forth thereby. The looking operation is the reverse, exceptthat as disk E is turned backward in throwing dog C into engagement withthe bolt, its cam E3 disengages lever F and spring J instantly shiftsthe lever so as to disengage clutch G from segment H. Thus in order tooperate the bolt it is necessary, first, to disengage dog C therefrom,and, second, to properly rotate disk E, so as to operate lever F, andboth these operations should occur, and by a proper key can be produced,simultaneously.

Having described my invention, what I claim as new, and desire to secureby Letters Patent thereon, is-

1. The combination of the sliding bolt, the revoluble shaft, the segmentloosely mounted thereon, and the oscillating lever and devices forcausing said segment to revolve with the shaft when the lever is shiftedin one direction, substantially as described.

2. The combination of the toothed bolt, the revoluble shaft and toothedsegment loosely mounted thereon engaging the bolt, and the oscillatinglever and devices for causing said segment to revolve with the shaftwhen the lever is shifted in one direction, with the revoluble cam-diskfor shifting said lever, adapted to be operated by a key, substantiallyas specified.

5.. The combination of the sliding bolt, the revoluble shaft, thesegment loosely mounted thereon, the oscillating lever and devices forcausing said segment to revolve with the shaft when the lever is shiftedin one direction, and the dog for positively locking said bolt,substantially as set forth.

4. The combination of the sliding bolt, the revoluble shaft, the segmentlooselymounted thereon, the oscillating lever and devices for causingsaid segment to revolve with the shaft when the lever is .shifted in onedirection, the cam-.disk for operating said lever, a dog for positivelylocking the bolt, and the tumbler for locking the dog, substantially asdescribed.

5. The combination of the sliding toothed bolt, the toothed segmentengaging the same,
